I was told by T-Mobile rep that rooted phones would not get update. I didn't care. Some said in forums and among friends that ICS not so good. I dont know about folk here and other phorums, my friends will hack own brain. Grain of basalt for my friends opining. Some said it was - ICS - cool. So I unrooted my phone in fit of hysteria, waited for update, none, so I decided to flash a stock rom of ICS. ICS - Android 4.0.2 Ice Cream Sandwich; it worked, except I couldn't download updates or apps from Google Play. The updates queue was getting longer. I search engined constantly for two days, tried all the solutions but none worked except: downloaded com.android.vending.playstore and installed it, it worked.
I searched for way to revert to Gingerbread. I tried two methods to root the ICS I had, didn't work.
Tonight, this morning, 0430 Central U.S.A. time I was looking for ways to return phone to Gingerbread, reached for phone to call a friend in Brussels, saw the message on screen, Software Update et cetera. The update finished I checked the phone information: SGH-T769, Android version 4.0.4, Baseband version T769UVMB1.
Apparently the stock ICS wiped out record of my rootings and flashings. I may flash a stock Jellybean if the hardware is a good fit. I'm sure if you have rooted phone in the past but bring it back to stock, you will be in the ota queue for updates again. I almost forgot, check xda for stock roms for the Blaze. ICS is now faster, lots of new stuff under the hood. Can't wait to root the sucker.
